Enter the required details into the microstrip calculator to determine the characteristic impedance of a microstrip line.
Microstrip Line Calculation Formula
The following formula is used to calculate the characteristic impedance of a microstrip line.
Z0 = (60 / √εr) * ln(8h / w + w / (4h))
Variables:
- Z0 is the characteristic impedance (Ω)
- εr is the relative dielectric constant of the substrate
- h is the height of the substrate (mm)
- w is the width of the microstrip (mm)
To calculate the characteristic impedance, use
